Upon installation and removal of the CIS, if obstacles such as dust intrude and remain in a compartment for the CIS, light to be received by the CIS is interrupted by the obstacles, and the interruption may undesirably affect image-reading quality of the image reading apparatus.
Meanwhile, the image reading apparatus may tend to weigh a considerable amount; therefore, carrying the image reading apparatus for installation and removal of the CIS may impose burden on the worker.
In other words, considerably large workspace is required for the entire image reading apparatus in the clean booth.
Moreover, when the image forming unit accompanied by the entire image reading apparatus is brought in the clean booth, it is likely that dust adhered to various parts of the image reading apparatus may also accompany the image forming unit to be brought in the clean booth.

Embodiment Construction
[0018]Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. A multifunction peripheral device (MFP) 1 will represent an image reading device according to the present invention.
[0019]Overall Configuration of the MFP
[0020]The MFP 1 is equipped with a plurality of image processing functions, which include a scanning function, a printing function, a copier function, and a facsimile transmission / receiving function. In the present embodiment, directions concerning the MFP 1 will be referred to in accordance with orientation indicated by arrows in the drawings.
[0021]The MFP 1 includes a main unit 2 at a bottom and a scanner unit 3 on top of the main unit 2. The scanner unit 3 is rotatable about a lower rear edge thereof, which corresponds to an upper rear edge of the main unit 3, to be openable and closable with respect to the main unit 2. Thus, the scanner unit 3 can shift postures thereof between a closed position (see FIG. 1B)...

An image reading apparatus to read an image formed on a document sheet is provided. The image reading apparatus includes a sheet conveyer and an image reader, which is controlled by a controller and reads the image formed on the document sheet. The sheet conveyer includes movable parts, which are movably supported by a first supporting member. The image reader is supported by a second supporting member, which is detachably attached to the first supporting member. A cable with a connector connects the controller and the image reader with each other via the connector. The second supporting member is tied to the first supporting member by the cable when the cable connects the controller and the image reader via the connector. The second supporting member is releasable from the first supporting member when the connector is decoupled.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority from Japanese Patent Application No. 2010-078668, filed on Mar. 30, 2010, the entire subject matter of which is incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]An aspect of the present invention relates to an image reading apparatus.[0004]2. Related Art[0005]An image reading apparatus having a contact image sensor (CIS) in an image reader unit is known. The CIS is generally arranged in a position along a document feeding path in the apparatus with a reading surface thereof facing the feeding path. Therefore, the CIS may be arranged on a frame of the apparatus with the other (non-reading) surface attached to the frame. When the CIS is installed in the apparatus, a worker may access the CIS through an opening, which is formed in the frame on a side opposite from the document feeding path across the CIS.[0006]The opening may be formed in a position to be covered by internal components ...
